DOOR AND LOCK FOR SAFE-DEPOSIT BOXES AND THE LIKE.

Specification of Letters Patent.

v Patented Oct. 5, 1915.

Application filed April 6, 1914. Serial No. 829,769.

To all whom it may concern:

Be it known that I, THOMAS S. SPIVEY, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Doors and Looks for Safe-Deposit Boxes and the like, of which the following is aspecification.

Heretofore in the construction of metallic doors for safe-deposit boxes and similar containers, it has been the practice to produce the door and the lock therefor as separate and distinct entities, and then to combine them by securing the lock to the internal face of the door. To this practice there are several objections. In the first place, the inward projection of the lock consumes space within the deposit-box, utilizable for holding securities; second, the construction of the lock as a complete entity necessitates providing it with an inclosing casing peculiar to itself, this involving substantial additional cost; and third, the projection of the look from the inner face of the door makes such lock liable to injury when the door is open. Under my invention, these objections to preexisting practice and constructions are overcome, as a result primarily of constructing the lock as part of the door itself, utilizing portions of the material of the door as the inclosing casing of the lock, and so arranging the look as that it shall lie flush with the internal face of the door, thereby guarding against accidental injury and assuring maximum capacity of the box to which the door is secured.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a front elevation of a safe-deposit box door provided with my improvement; Fig. 2 is a longitudinal section thereof on the line 22 Fig. 1; Fig. 3 is a transverse section on the line 3-3 Fig. 1; and Fig. 4 is a detail view of the inner face of a portion of the box door, showing the lock.

In carrying out the invention, I provide a safe-deposit box, preferably of metal and of any suitable size and shape and to the open end of this is hinged at a a metallic door B of substantial thickness, adapted to open outwardly. Said door is provided upon its inner face and toward the free end I 7 thereof with a recess C (best shown in Fig.

4), this recess having preferably perpendicular walls and being provided on either side thereof with depressions 0 provided with threaded orifices for the purpose presently explained.

'Within the recess C of the door B, I seat the lock D, provided with the bolt (Z adapted to coact with a suitable depression or nosing in the front edge of the side-member of the box A. Said lock preferably includes, in addition to the usual lock elements, the post cl extending through a suitable orifice in the door B, so as to be accessible from the outside, this post being provided with the usual key-hole slot permitting the bolt D to be operated upon the insertion therein of a suitable key. As will be seen, the locking device includes only the parts of a lock proper, the usual casing, completely surrounding the lock, or surrounding it completely save on the under side, being wholly dispensed with, the purposes of the casing being met by the bottom and walls of the recess C.

To secure the lock in position, I provide a cover-plate E, having, as shown in Fig. 1, ears 6 of such size as to fit snugly within the depressions 0, screws 6 being adapted to pass through said ears and into the threaded orifices in the bottom of said depressions 0, for the purpose of securely binding said cover-plate upon the lock. Preferably, for the purpose of properly positioning the look within the recess C, the key-hole post cl is of such length as that its rearward end shall operate in an opening (Z in the cover-plate E, such opening constituting a bearing for the rearward end of said post.

By means of the construction herein disclosed, I dispense entirely with the usual lock-casing, securing thereby reduction in the number of parts and consequent economy of production and ease of assemblage. Additionally, since the lock does not project beyond the internal face of the door, it is not in position to be struck and accidentally injured. Finally, no part of the space within the safe-deposit box otherwise utilizable, as for securities etc., is taken up by the lock, as has heretofore been the case.

Having now described my invention, what I claim as new therein and desire to secure by Letters Patent is as follows 1. A metallic door for safe-deposit boxes and the like, of solid construction, and substantial and approximately uniform thickness, the same being provided with a recess in its internal face, a lock secured in position within said recess, and a cover-plate fixedly secured over said lock and lying in said recess, with its exposed face substantially flush with the internal face of said door, said lock including a key-hole post the forward end of which lies substantially flush with the outer face of said door, its inner end operating in a bearing in said cover-plate, substantially as set forth.

2. A metallic door for safe-deposit boxes and the like, of substantial and approximately uniform thickness, the same being provided with a recess in its internal face, a lock secured in said recess, and a cover-plate in said recess extending over said lock and lying with its exposed face flush with the Copies of this patent may be obtained for internal face of said door, said lock including a key-hole post the end whereof passes through said door and lies flush withthe outer surface thereof, its rearward 'end coacting with abearing in said cover-plate, said cover plate being provide with ears engaging in depressions in the inner face of said door and having exposed surfaces flush with said inner face, and with securing means whereby said ears are secured in said depressions, substantially as set forth.

This specification signed and witnessed this 30th day of March 1914.
